Description

Technical Field

[0001] This utility model mainly relates to the field of rice-shrimp farming wastewater treatment technology, specifically to a rice-shrimp farming wastewater treatment device. Background Technology

[0002] Rice-crayfish co-cultivation, as a form of ecological agriculture, has been widely promoted in rice-producing areas of my country in recent years, achieving the comprehensive benefits of "dual use of water and double harvest from one field." The wastewater generated during the aquaculture process contains high concentrations of pollutants, mainly including crayfish excrement, leftover feed, fertilizer residues, and pesticides. Most farmers discharge this wastewater directly into natural water bodies through ditches. Excessive nitrogen and phosphorus in the wastewater, once entering rivers and lakes, stimulates explosive algal growth, leading to a sharp drop in dissolved oxygen and disrupting the balance of the aquatic ecosystem. Residual chemicals are toxic to benthic organisms and fish, and long-term accumulation may harm human health through the food chain. Some small-scale farmers use simple soil sedimentation ponds for filtration, but this method cannot effectively remove dissolved pollutants, and the sludge is difficult to clean. Utility Model Content

[0004] This utility model provides a rice-shrimp farming wastewater treatment device to solve the technical problems existing in the background art.

[0005] 2. Technical Solution:

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: a rice-shrimp farming wastewater treatment device in rice cultivation, including a filter sedimentation tank, a filter frame detachably installed inside the filter sedimentation tank, a sedimentation plate provided below the filter frame, the outer wall of the sedimentation plate being sealed to the inner wall of the filter sedimentation tank, and a lifting mechanism connected to the bottom for driving it to rise and fall vertically along the inner wall of the filter sedimentation tank.

[0007] A scraper and a horizontal drive mechanism for driving the scraper to move horizontally along the upper surface of the sedimentation plate are provided between the sedimentation plate and the filter frame.

[0008] The filter sedimentation tank has a first outlet on one side wall, which is located on the side of the scraper and a sediment collection tank is provided below it. The filter sedimentation tank has a second outlet on the side wall adjacent to the first outlet, and the bottom height of the second outlet coincides with the top height of the first outlet. A supernatant collection tank is provided below the second outlet, and the supernatant collection tank is connected to the aeration tank through a pump.

[0009] Furthermore, a limiting frame is fixed to the top of the filter frame, and several sets of linearly distributed positioning blocks are symmetrically arranged on both sides of the bottom of the limiting frame. Each positioning block has a first locking hole through it. The top of the filter sedimentation tank has several sets of positioning slots that match the positioning blocks. Each positioning slot has a second locking hole through it. When the positioning block is inserted into the positioning slot, the first locking hole and the second locking hole on the same side form a continuous channel, and locking is achieved by inserting a pin.

[0010] Furthermore, hand grips are symmetrically provided on both sides of the top of the limiting frame.

[0011] Furthermore, the lifting mechanism includes a linear actuator fixed to the bottom of the filter sedimentation tank. The output shaft of the linear actuator is vertical, and its end is fixed to the center of the bottom of the sedimentation tray. The linear actuator is symmetrically provided with vertical guide sleeves fixed to the bottom of the filter sedimentation tank on both sides. Each vertical guide sleeve is equipped with a guide rod with clearance fit. The top of the guide rod is fixed to the bottom of the sedimentation tray.

[0012] Furthermore, the horizontal drive mechanism includes two sets of horizontal guide rails fixed to the inner wall of the filter sedimentation tank. Convex sliders are symmetrically fixed on both sides of the top of the scraper. Each convex slider is slidably connected to the corresponding horizontal guide rail. A lead screw with the same extension direction is rotatably installed in one of the horizontal guide rails. The lead screw is threadedly engaged with the convex slider on the same side, and one end extends to the outside of the filter sedimentation tank and is equipped with a drive motor.

[0013] Furthermore, the second outlet is located below the horizontal guide rail.

[0014] 3. Beneficial effects:

[0015] Compared with the prior art, the technical solution provided by this utility model has the following advantages: After the effluent is introduced into the filtration sedimentation tank, the particulate pollutants are first filtered through the filter frame. After the sediment precipitates at the top of the sedimentation plate, the clear liquid separated from the sediment can be discharged into the supernatant collection tank through the first outlet by the lifting mechanism. Then, it is pumped into the aeration tank for further treatment until the discharge standard is met, thereby avoiding environmental pollution. In addition, the horizontal drive mechanism drives the scraper to move horizontally along the upper surface of the sedimentation plate, which can scrape the sediment into the sediment collection tank, thereby achieving simple and quick collection of sediment.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0027] See attached document Figure 1-5 A rice-shrimp farming wastewater treatment device includes a filter sedimentation tank 1, a filter frame 2 is detachably installed inside the filter sedimentation tank 1, a sedimentation plate 3 is provided below the filter frame 2, the outer wall of the sedimentation plate 3 is sealed to the inner wall of the filter sedimentation tank 1, and a lifting mechanism 4 is connected to the bottom to drive it to rise and fall vertically along the inner wall of the filter sedimentation tank 1.

[0028] A scraper 6 and a horizontal drive mechanism 5 are provided between the sedimentation tray 3 and the filter frame 2 to drive the scraper 6 to move horizontally along the upper surface of the sedimentation tray 3.

[0029] The filter sedimentation tank 1 has a first outlet 101 on one side wall, which is located on one side of the scraper 6 and a sediment collection tank 7 is provided below it. The filter sedimentation tank 1 has a second outlet 102 on the side wall adjacent to the first outlet 101. The bottom height of the second outlet 102 coincides with the top height of the first outlet 101. A supernatant collection tank 8 is provided below the second outlet 102. The supernatant collection tank 8 is connected to the aeration tank 10 through a pump body 9.

[0030] In this embodiment, after the effluent is introduced into the filtration sedimentation tank 1, the particulate pollutants are first filtered through the filter frame 2. Then, a precipitant is added to the tank through the first outlet 101 or the second outlet 102. The tank is left to stand and wait for the sediment to precipitate at the top of the sedimentation plate 3. Next, the first outlet 101 is opened, and the sedimentation plate 3 is driven to rise in the filtration sedimentation tank 1 by the lifting mechanism 4. The water level in the filtration sedimentation tank 1 rises synchronously. The clear liquid separated from the sediment enters the supernatant collection tank 8 through the first outlet 101, and then enters the aeration tank 10 through the pump body 9 for further treatment until the discharge standard is met. The lifting mechanism 4 continues to drive the sedimentation plate 3 to rise in the filtration sedimentation tank 1 until its top touches the scraper 6. At this time, the second outlet 102 is opened, and the scraper 6 is driven to move horizontally along the upper surface of the sedimentation plate 3 by the horizontal drive mechanism 5, so that the sediment can be scraped into the sediment collection tank 7.

[0031] The filter frame 2 is fixedly provided with a limiting frame 201 at the top. Several sets of linearly distributed positioning blocks 202 are symmetrically arranged on both sides of the bottom of the limiting frame 201. Each positioning block 202 is provided with a first locking hole 203. The top of the filter sedimentation box 1 is provided with several sets of positioning slots 103 that match the positioning blocks 202. Each positioning slot 103 is provided with a second locking hole 104. When the positioning block 202 is inserted into the positioning slot 103, the first locking hole 203 and the second locking hole 104 on the same side form a continuous channel, and locking is achieved by inserting a pin 11.

[0032] In this embodiment, the filter frame 2 is abutted against the top of the filter sedimentation tank 1, and each positioning block 202 is inserted into the positioning slot 103. At this time, the first locking hole 203 on the same side is aligned with the second locking hole 104. Then, the pin 11 is inserted into it to complete the installation of the filter frame 2. Similarly, it can be disassembled.

[0033] In the above embodiment, hand grips 204 are symmetrically arranged on both sides of the top of the limiting frame 201.

[0034] The lifting mechanism 4 includes a linear actuator 401 fixed to the bottom of the filter sedimentation tank 1. The output shaft of the linear actuator 401 is vertical, and its end is fixed to the center of the bottom of the sedimentation plate 3. The linear actuator 401 is symmetrically provided with vertical guide sleeves 402 fixed to the bottom of the filter sedimentation tank 1 on both sides. Each vertical guide sleeve 402 is provided with a guide rod 403 with clearance fit. The top of the guide rod 403 is fixed to the bottom of the sedimentation plate 3.

[0035] In this embodiment, after the linear actuator 401 is activated, the sedimentation plate 3 can be driven to rise and fall within the filter sedimentation box 1. In addition, the vertical guide sleeve 402 guides the sliding guide rod 403, making the rising and falling process of the sedimentation plate 3 more stable.

[0036] The horizontal drive mechanism 5 includes two sets of horizontal guide rails 501 fixed to the inner wall of the filter sedimentation tank 1. The top two sides of the scraper 6 are symmetrically fixed with convex sliders 502. Each convex slider 502 is slidably connected to the corresponding horizontal guide rail 501. A lead screw 503 with the same extension direction is rotatably installed in one of the horizontal guide rails 501. The lead screw 503 is threadedly engaged with the convex slider 502 on the same side, and one end extends to the outside of the filter sedimentation tank 1 and is equipped with a drive motor 504.

[0037] In this embodiment, after the drive motor 504 is started, the lead screw 503 connected to its output end rotates synchronously, which drives the convex slider 502 that is threaded to it to slide in the corresponding horizontal guide rail 501. Another convex slider 502 slides synchronously in the corresponding horizontal guide rail 501, which drives the scraper 6 to move horizontally.

[0038] In the above embodiment, the horizontal guide rail 501 can block the tailwater filtered by the filter frame 2, thereby avoiding direct impact on the sliding of the lead screw 503 and the convex slider 502 with the horizontal guide rail 501. Furthermore, the second outlet 102 is located below the horizontal guide rail 501, so the clear liquid separated from the sedimentation will not directly contact the horizontal drive mechanism 5 and affect it when it rises with the sedimentation plate 3.

[0039] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.

[0040] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art.
